Long range weather forecast

This long range forecast for the UK is updated once a month. Using the latest long range data from the NCEP and then run through custom software here at Netweather it is on the cutting edge of technology for long range weather forecasting. It is important to bear in mind that forecasting at this range is still in its infancy so can effectively be considered experimental.

Summer into Autumn 2014

Updated July 22nd 2014
We're midway through the Summer, we've kept the run of warmer than average months going (7 in a row now), will that continue as we close out the Summer and head into Autumn?

August
With pressure forecast to be higher than average right from Scandinavia, across the northern half of the UK and out into the Atlantic, a good deal of settled weather can be expected. Even so, the forecast is for rainfall to be close to average for much of the UK, with showery periods of rain the most likely source of many of the wetter spells - meaning some significant local variations are likely. Temperatures are forecast to be warmer than average countrywide.

September
The start of meteorological Autumn is forecast to bring a very typical UK weather pattern with pressure expected to be lower than average to the northwest of the British Isles, and higher than average over central and eastern Europe. This setup points toward the northwest of the country being wetter than average, but close to, or drier than average further south and east. Once again, temperatures are forecast to be warmer than the seasonal norm.

October
As ever at this range confidence does tend to really fall away, but the current outlook suggests that the Azores high may regularly ridge toward the British Isles, leading to a drier than average month for much of the UK. Temperatures at this stage are forecast to be close to or milder than normal.

The long range weather forecast displayed on this page is based on data from the Climate Forecast System from the NCEP (USA), run out to 9 months in advance and are updated once a month. The raw data is sent daily to Netweather, our systems then average and further process that data to produce the forecast you see below. The average figures you see on the forecast are not the standard 1971 to 2000 figures you may often see, instead they are rolling averages, currently from the period 1980-2008.
